I'm a 4.0 counterpuncher, 5 foot 7, not a muscular guy. I play mostly singles. I use a semi-western forehand grip, double handed backhand. My weakness is my net game, but I'm fairly consistent with the rest. I usually play on weekends and twice during the week. Singles mostly. Tennis elbow has started to bother me, so comfort has become a priority. I keep hearing and reading good things about Pro Kennex frames. I'm getting a demo of the Pro Kennex 5G classic next week, but I don't like to demo more than one racquet at once (my current racquet is the Head Liquidmetal Midplus, stock). I use Wilson NXT tour at mid tension. However, I've noticed that there is a similar model, the Pro Kennex Kinetic Ki5 315, but a bit more expensive. Which one is better for you and why? Your input is much appreciated. Thanks!
